Dear Matthieu,<br>
<br>
Best way is to drill a hole in the duct with the equipment connected
to the exhaust. Then you will have a correct reading of the exhaust.
You can ask for the use of duct putty to properly clug the drilled
holes on toxic exhaust.<br>
<br>
Good luck !<br>
Best regards,<br>

Colleagues,
<div><br>
</div>
<div>First, thank you for the handful of information about bending
coax tubing. </div>
<div><br>
</div>
<div>Now, facilities services here at McGill want to assess our
ventilation/exhaust capacity. To measure exhaust they want to
drill 3/8'' holes into each duct leading to a tool, take a
reading and plug it back. They show me the plugs they want to
use and I’m not convinced at all especially for the gas cabinet
exhaust. They don’t want to un-connect the tool and measure
directly as they want to make its resistance is taken into
account. </div>
<div><br>
</div>
<div>Any body has experience regarding that matter ?</div>
<div><br>
</div>
<div>Thanks in advance</div>
<div><br>
</div>
